I mean length, sorry about that. I can't include a screenshot right now, as I'm using my phone, but the main thing I want to do is be able to adjust the length of the announcements the same way it let's you adjust the height.Also, to customize the width, color, and style of the border pixels would be nice, but if possible I'd like to attach a bitmap (or other image file) to the box as a border, or perhaps a background - in much the same way as you can do with the nav buttons or forum category titles. The main thing is adjusting the length, though, so how can I do that?

You can change width: 1200px; to a different number if you wish. The larger the number, the longer the announcements box and vice-versa. A word of warning, however, if the announcements box exceeds the forum width, then your forum width will increase as well.

For your other customisations, I may be able to help you with that but I will need you to provide more details.
